Here’s the full glyph set of François Lasgi’s Puff Wind III as shown in a Mecanorma catalog from 1974, incl. alternates for A, E, H, M. If there ever were Puff Wind I and II, these might have been solid and outlined versions without shadow which were not deemed worthy of inclusion. The only other Mecanorma face with a Roman numerals suffix was Roberta III.
